The Z1 Motorsports Rear Differential Bushing Sleeve combines simplicity and convinience by allowing you to skip extra steps when installing aftermarket differential bushings (such as Energy Suspension) that require re-use of the factory bushing sleeve. The Z1 Motorsports Rear Differential Bushing Sleeve is modeled after factory specifications, and its zinc plated 4130 alloy steel provides exceptional strength and corrosion resistance necessary for a long service life.
When using Energy Suspension (or similar bushings), the factory differential bushing sleeve that is molded to the stock fluid-filled bushing must be burned out and cleaned. This not only adds to install time, but is also typically a messy procedure.
Z1 also offers a differential bushing press designed to ease removal of the stock bushing and can be purchased separately HERE.
